Food web interactions at the edge of the Arctic: Foxes and lemmings in northern Manitoba.

Dr. Roth’s lab studies interactions among Arctic foxes and their prey near Churchill, Manitoba, on the west edge of Hudson Bay, where boreal forest transitions to Arctic tundra. This site is near the southern edge of many Arctic species’ distributions, where the impact of climate change is likely to be large. Arctic foxes are important predators on lemmings, seals, and migratory birds, and changing environmental conditions may affect the way these species interact, which are sometimes counter-intuitive.
